Several analog-to-digital conversion methods for bandlimited signals used in applications, such as quantization schemes, employ coarse quantization coupled with oversampling. The...
Abstract--In this paper, we propose a robust STBC transmission scheme to combat timing synchronization errors over frequency-selective multiple-access channels. We start by derivin...
: A secure electronic cash scheme and its role-based access control (RBAC) management are proposed in this paper. The scheme uses electronic cash for payment transactions. In this ...
A three-dimensional (3D) CMOS imager constructed by stacking a pixel array of backside illuminated sensors, an analog-to-digital converter (ADC) array, and an image signal process...
The article proposes a simple, scalable and robust scheme for the distribution of revocation information in mobile ad hoc networks (MANETs). The scheme is intended for ad hoc netwo...
